ELEVATOR-GUIDE LUBRICATOR.

Application filed June 1 2, 1922. Serial No. 567,610.

This invention relates to elevator guide lubricators.

The object of this invention is to provide a simple, eificient and positively actuated device for applying a lubricant to elevator guides.

The advantages of this invention will appear in the following specification in which I will describe the present invention, reference being had to the accompan ing drawings forming a part of this application and in which,

Fig. 1 is a sectional elevation of an elevator guide lubricator which is made according to and embodies my invention.

Figs. 2 and 3 are sectional plan views of the device, the sections in these figures being taken on the lines 2-2 and 33 respectively of Fig. 1.

Fig. 4 is a sectional elevation of a part of the device showing the positively actuated valve in raised position.

Like characters of reference designate corresponding parts in all the views of the drawings.

10 designates an elevator guide and 11 a art of a guide shoe of usual form carried y an elevator car (not shown). 12 is an angle bracket afiixed to the guide shoe by bolts 13 which extend through slots so that its position may be adjusted. The improved lubricator comprises a casing 20 which is afiixed to the angle bracket by bolts 14 which also extend through slots for the purpose of providing for adjustment of the position of the casing on the bracket.

The casing 20 forms a chamber for the reception of oil and is provided with a cover 21. Its lower end is extended to form a shelf 22 which is notched to fit the guide 10 loosely. The outside of this shelf is provided with a flange 23. A wick 24 of absorbent material is placed on this shelf and held in position by a cover 25. The bottom of the casing is constructed with a vertical conical depression 26 which forms a valve seat and with an oil duct 27 leading from this depression to the wick 24. A threaded transverse hole 28 is made from one side of the casing to the oil duct for the reception of an adjusting screw 29.

Inside of the casing is a bracket 30 which slidabl supports a plunger 31, the lower end of which is tapered to form a valve which fits the conical depression 26. 32 is a spring interposed between an upper arm of the bracket 30 and a washer 33 and functions to press the plun er 31 into the depression 26 to form an oil tight closure. The upper part of the plunger 31 is constructed with flattened sides 34, the upper ends of which terminate in shoulders 35.

A shaft 40 extends transversely through the sides of the casing 20 in whichit is rotatively supported. Afiixed to this shaft inside of the casing is an arm 41, one end of which is bifurcated as at 42 to fit loosely over the flattened sides 34 of the plunger. On the outside of the shaft 40 is a connector 43 which is non-rotatively aflixed to the 7 shaft. This also supports an actuating arm 44 which extends toward the elevator guide 10.

50 is a fixed member which is attached to the elevator guide as shown in Figs. 1 and 3. This member comprises an abutment 51 which extends toward and into the path of movement of the arm 44.

When the car on which this device is mounted ascends, the actuating arm 44 8 strikes the abutment 51 and is depressed thereby. This causes the bifurcated end 42 of arm 41 to engage the shoulders 35 and to raise the plunger 31 to the position in which it is shown at 31 in Fig. 4. The upper surfaces of this bifurcated end of arm 41 are curved to facilitate this part of the operation. This permits oil from the chamber which is formed by the casing 20 to flow to the wick 24 which distributes it on the guide rail 10. The flow of oil through the duct 27 is controlled by the screw 29, the position of which is adjustable.

When the car descends the actuatin arm 44 is raised b the abutment 51 a su cient 96 amount to al ow it to pass, the flattened sides 34 of the plunger being of sufficient length to permit the end 42 to move downwardly without obstruction at such times. As soon as arm 44 has passed the abutment the weight of the actuating arm restores the arm 41 to the position in which it is shown in Fig. 1 and it will be held in this position by the engagement of its end 42 with the shoulders 35 until it is actuated again.

By this simple arrangement lubrication may be applied to elevator guides regularly, in desired quantities and with even:d1s tribution.

hat I claim is:

1. An elevator guide lubricator comprising a casing forming arese-rvoir, an integral flanged shelf extending from the bottom thereof notched to straddle an elevator guide, a communicating passage between thereservoir and the shelf and constructed to form a valve seat, a wick on said shelf, a bracket in the casing, a plungerguided in the bracket, aspring between a part of the bracket and a part of the plunger, pressing the plunger against the valve seat, a shoulder on the plunger, a transverse shaft projecting through the casing, a movable arm affixed to the shaft within the casing arranged to engage said shoulder when moved in one direction, and to clear the plunger when moved in the opposite direction, an actuating arm connected with the shaft outside the casing and an abutment member adapted to be aflixed to an elevator guide in the path of movement of said actuating arm.

2. An elevator guide lubricator comprising a casing forming a reservoir, an integral flanged shelf extending from the bottom thereof notched to a straddle an elevator guide, a communicating passage between the reservoir and the shelf and constructed to form a valve seat, a wick on said shelf, a bracket in the casing, a plunger guided in the bracket, a spring between a part of the bracket and a part of the plunger, pressing the plunger againset the valve seat, a shoulder on the plunger, a transverse shaft projecting through the casing, a movable arm at fixed to the shaft within the casing having a curved end, arranged to engage said shoulder when moved in one direction, and to clear the plunger when moved in the opposite direction, an actuating arm connected with the shaft outside the casing and arranged by its weight to hold said first mentioned arm in contact with the shoulder on the plunger and an abutment member adapted to be afhxed to an elevator guide in the path of movement of said actuating arm.

3. An elevator guide lubricator comprising a casing forming a reservoir, an integral flanged shelf extending from the bottom thereof notched to straddle an elevator guide, acommunicating passage between the reser voir and the shelf and constructed to form a valve seat, a wick on said shelf, a bracket in the casing, a cylindrical plunger guided in the bracket, a spring between a part of the bracket and a part of the plunger, pressing the plunger against the valve seat, said plunger being depressed near its end away from the valve seat to form shoulders, a transverse shaft projecting through the easing, a movable arm aflixed to the shaft within the casing, having a bifurcated end clearing the depressed portion of the plunger and having curved surfaces arranged to engage said shoulders, an actuating arm connected with the shaft outside the casing and arranged by its weight to hold said curved surfaces of the first mentioned arm in contact with shoulders on the plunger, and an abutment member adapted to be affixed to an elevator guide in the pathof movement of said actuating arm; 7

4.
